LeakageMath, a collaboration between the Society of Cable Telecommunications Engineers (SCTE) and ComSonics, Inc., offers an electronic version of the SCTE "Useful Leakage Formulas" Operational Practice (SCTE 222 2016) and provides the featured formulas in a calculator format. While specifically pointing to signal leakage, a bit of imagination allows use of some of the calculation and conversion formulas for general decibel-related math.
